Students learn through lecture the differences between asteroids, meteors, and
comets. Look at composition, where they are located, etc.
Students close their eyes and imagine an asteroid in space. This is their new discovery!
As scientists, students must work together and individually to build a 3-D model of the
asteroid.
Students get into groups, mix dough (following the recipe), and allocate a ball of dough
for each student.
Students will add different foods to their dough to represent different minerals.
Students must draw and label the asteroid to show the different parts for “other”
scientists. Then they must come up with a name. Extension: Children create a story
around their asteroid.
The next day students will re-visit the idea of asteroids, meteors, and comets. Will look
at how they make craters upon impact. Show pictures of craters on earth, moon, etc.
Students get in groups and explore the impact of craters using balls and shoeboxes filled
with flour, salt, and a sprinkle of cinnamon on top.
First, students crouch and drop different sized balls. Then they stand and drop from
shoulder-height.
Class comes back together and talks about their observations and hypothesis.
Assessment:
Each child must complete a 3-D model of an asteroid, along with their drawing. Each drawing must
include labels of minerals and craters, and a name for the crater.

Comets, Meteors and Asteroids
(Links | Questions)
Comets, asteroids, and meteors are often grouped together since they are all basically the same
thing: small pieces of rock and/or ice that aren't part of a major planet.
Comets
Comets are objects composed mostly of ice and dust that grow tails when they approach the sun.
All comets have a nucleus, which is the hard rock/ice object. When a comet nucleus nears the
sun, solar energy begins to heat the ice and vaporize it. The gas flies off the comet, sometimes
violently enough to break the nucleus apart, and throws dust up with it. The gases form a cloud
around the nucleus called the coma. Some of the gas is stripped of electrons and blown back by
the solar wind. This forms a bluish colored ion tail. The dust particles are pushed away from the
comet by solar radiation, forming a dust tail that can be many millions of miles long. The dust
tail is the easiest to see with the unaided eye, but occasionally the ion tail is visible as well. Each
time a comet passes close to the sun, it loses more of its ice. Eventually, after many passes, the
comet may no longer have enough material to form tails. Its surface will be covered by dark dust
and it will look more like an asteroid.
Comets come from two places in the Solar System: the Oort Cloud and the Kuiper Belt. The Oort
Cloud is a spherical halo of comets surrounding the Solar System at a distance of around 50,000
Astronomical Units. (One Astronomical Unit equals the distance from Earth to the Sun.) Comets
from the Oort Cloud have long orbital periods and can enter the solar system from many
different directions. The Kuiper Belt is a ring of icy objects beyond the orbit of Neptune (30-100
AU). It lies (more or less) in the plane of the solar system and is a reservoir for the short period
comets that we see. The first Kuiper Belt Objects (KBOs) were discovered in the early 90s, and
they captured the interest of astronomers because they are probably the oldest, most pristine
material in the solar system. Studying KBOs is difficult because they are distant and very small,
but more have been discovered over the last few years as telescope and instrument technologies
have improved. Astronomers now know of a few hundred KBOs, including a large object called
Quaoar which is half the size of Pluto. Quaoar is the largest solar system object discovered since
Pluto and Charon, and it reinforces the idea that there might be other large KBOs that are still
undiscovered.
Asteroids
Asteroids are the small rocky objects in the Solar System. The largest asteroid is Ceres, which is
933 kilometers (580 miles) across. The smallest asteroids that we've observed in detail are only
tens of meters in size, but there are probably a great number of small rocks in space that are
currently too small for us to detect. Many asteroids, including all of the largest asteroids, orbit
the sun between Mars and Jupiter in the Asteroid Belt. The Trojan asteroids share Jupiter's
orbital path, but stay 60 degrees ahead or behind Jupiter. Near-Earth Asteroids orbit the sun in
the vicinity of the rocky terrestrial planets and pose the greatest threat to Earth. We think that the
total mass of all the asteroids combined is less than that of the Moon.
The asteroid population is amazingly diverse - each one seems different! Some asteroids such as
Mathilde are very light and are probably "rubble piles" made up of lots of small particles loosely
held together. Other asteroids are metallic (for example Kleopatra) or pieces of solid rock (Eros,
visited by the NEAR spacecraft, is an example) . Sometimes asteroids have small moons or
travel in equal-sized pairs. Most asteroids have unusual shapes because they have experienced
many collisions and do not have a strong enough gravity to pull themselves back into a sphere.
Asteroids are not visible to the unaided eye, but some can be seen with small telescopes or even
binoculars.
Meteors
Meteors are the short, white trails across the sky that we call "shooting stars." They are caused by
small pea-sized pieces of inter-planetary dust that burn up when they slam into the Earth's
atmosphere at high speeds. Meteor showers happen when Earth passes through the orbital path of
a comet that left a lot of dust behind. Earth plows through the dust, and the particles form
meteors as they hit the atmosphere. Occasionally a small rock may fall through the atmosphere,
causing an extremely bright and colorful streak across the sky called a fireball. (These are often
mistaken for comets, but comets do not streak across the sky quickly; they are usually visible for
many days.) Sometimes fireball rocks are not completely vaporized, and they impact Earth's
surface. A rock that fell from space this way is called a meteorite.

The Magic School Bus Out of This World
Field Trip Notes
According to Dorothy Anns research, an asteroid is going to collide with Walkerville Elementary!
To save the school, the class rockets into space to try and follow the asteroids path. There, the
kids see comets, meteors, and other space objects. When the moons gravity pulls them off course,
the kids discover that the bigger the object, the greater its gravitational pull. DA comes up with
an out-of-this-world plan: Theyll find the asteroid, change its course, and fling it into the sun! Can
the kids boldly go where no class has gone before? Or will school be out...forever?
Going Hands-On
Time: 30 minutes
Group Size: Four
If the asteroid Ms. Frizzles class followed crashed to Earth, it would create a huge crater. Your
kids can explore the craters that objects of different sizes and weights - marbles, Ping-Pong balls,
and aluminum-foil balls - create.
What You Need






Small jar of cinnamon
Marbles, small and large
Aluminum-foil balls
Ping-Pong balls
Spoon
Copies of CRATERS
For each group:


4 cups of salt and 4 cups of flour
Shoe box
Ahead of time: Mix flour and salt together in shoe boxes. Smooth the surface flat and cover with a
light layer of cinnamon.
Talk About It
Hold up the balls. Ask: What might we see if we dropped these into the shoe boxes?
What To Do
1. From crouching positions, kids drop the balls into the shoe boxes and then carefully
remove balls. Ask: What do you see? (craters of different size and depth; some bigger then
objects; may see “spokes” of cinnamon or small mounds of four/salt mixture around
craters) Have students draw their craters.
2. Ask: What might happen if we dropped the balls from higher up? (They would fall harder.)
3. Have kids drop balls into the box from shoulder height. Ask: What do you see? (bigger,
deeper craters) Why did that happen? (Balls had more time to pick up speed; faster balls
make bigger holes.) Have kids draw these craters and compare with their first craters.
Next Stop
Ask: What might happen if we dropped objects that aren’t round into the shoe boxes? Try it!

Edible Asteroids
Asteroids are rocky, metallic objects that orbit the sun. Asteroids are believed to be the remains of a planet collision
that occurred shortly after the formation of the solar system. Another theory is that asteroids were pieces of a
potential planet that was never able to become a complete planet and dissipated into the solar system. Regardless of
how asteroids were formed, scientists have been able to observe their unique shapes and sizes. Asteroids range in
sizes from 1000 km in diameter to the size of pebbles. The larger asteroids have crater marks on their surface, similar
to that of the moon.
Here is your opportunity to make your own edible asteroids. You will need the following supplies:
Ingredients
Utensils
Potatoes: enough to make 4 to 8 cups of mashed
potatoes
Electric mixer to make the mashed potatoes
1/2 stick of butter
Cookie sheet
Salt
Oven mitt
Pepper
Mixing bowl and spoon
Step 1.
Preheat the oven to 375 degrees
Step 2.
Take a small slice of butter and rub onto cookie sheet. It will help keep your asteroids from sticking to the sheet.
Step 3.
Make the mashed potatoes, add butter and salt and pepper to taste. Mix well. The mixture should stick together. If it
is too dry, add a little milk. If it is too moist, add a little flour (start with 2 tablespoons).
Step 4.
Take a handful of mashed potatoes and shape into your own asteroid. Be sure to poke holes in your asteroids
to look like craters.
Step 5.
Set your asteroid on the greased cookie sheet.
Step 6.
Put your cookies sheet of potato asteroids in the oven and bake for 20-25 minutes or until brown around the edges.
Step 7.
Remove your asteroids from the oven using an oven mitt and place on a serving plate. Let sit for 5 minutes to cool
down.
Step 8.
Enjoy your asteroids.

into account such things as the model’s purpose and complexity.
Understandings:
Students will understand that
comets, meteors, and asteroids have
impacted our solar system and the planets
and moons contained in it.
Essential Question:
How would the Earth be different if there
were no comets, meteors, and asteroids in
space?
Students will know
the physical characteristics of
comets, meteors and asteroids;
where comets, meteors and
asteroids are most likely to be
found; and
how craters are formed.
Students will be able to
differentiate between comets,
meteors, and asteroids;
keep accurate and clear records
while observing a meteor shower;
label the parts of a comet;
discuss how Earth and the other
planets in the solar system have
been affected by comets, meteors,
and asteroids; and
indicate the probable location of
comets, meteors, and asteroids on
a map of the solar system.
Lesson Hook:
Show all or part of the movie Asteroid. Lead a discussion of the movie with the
students. Ask how realistic they believe the movie to be, and to give reasons for
Grade 6 Earth Science Standard 1f 75 Comets, Asteroids, and Meteors, Oh My!
their beliefs.
Complete the “Noblesville Fall” lesson from the NASA publication Exploring
Meteorite Mysteries, available through the NASA Resource Center (see
resources) or online at http://wwwcurator.
jsc.nasa.gov/outreach1/expmetmys/Lesson1.pdf
Assessment
Performance Tasks:
Performance Task #1: Milky Way Amusement Park Students are hired as
contractors to create new rides for the Milky Way Amusement Park. Students may
choose among comets, meteors, and asteroids for their rides. They must write a
proposal for the ride, describing in detail where the ride will be located, how the
customer will get to the ride, what the ride looks like, how the customer will feel on
the ride, where the ride ends up, cost of the ride, etc. A model or diorama depicting
the ride will also be created. A rubric will be used to grade the proposal and model.
Students will be given a copy of the rubric when the assignment is made, and it
should also be used for student self-assessment.
Construct a model of a comet with its parts correctly labeled.
Write a science fiction story involving a comet, meteors, or asteroids. Even though
the story is science fiction, the details concerning the comet, meteors, or asteroids
must be scientifically accurate.
Write an acrostic poem for the words comet, asteroid, and meteor.
Other Evidence:
Make 3 paddles for each student out of 3 different colors of construction paper and
wooden craft sticks. Label one color comet, one color asteroid, and one color meteor.
Call out characteristics of one or more of the object(s). Students are to hold up the
corresponding paddle(s). (Example: “made of dust and ice” – student holds up comet
paddle) Teacher can quickly evaluate student comprehension.

Grade 6 Earth Science Standard 1f 76 Comets, Asteroids, and Meteors, Oh My!
Plan of Action
Learning Activities:
Activity Sheet #1: Compare and contrast comets and asteroids by researching their
characteristics from the Internet or other resources and by completing the Comets and
Asteroids comparison chart.
Research major meteor showers to find out when they occur. In cooperative learning
groups, have students combine individual data to create a timeline. Explain why meteor
showers are visible at about the same time each year.
Activity Sheet #2: Observe a major meteor shower (e.g. Lyrids in April, Perseids in
August, Leonids in October etc.) Students should use the meteor-shower observation
sheet to record data.
Collect meteorites by placing a large plastic container of distilled water outside for two
weeks during various meteor showers throughout the year. Using a magnet, collect the
meteorites from the bottom of your container. You may wish to place a container outside
of your classroom instead of assigning this as an individual project.
Research the media for incidences of comet sightings and the reactions of observers.
Explain how comets are tracked and why they are not visible every year as meteor
showers are.
Make edible comets and asteroids. Provide a variety of ingredients and let
students use
their imaginations to create their comet and/or asteroid. (Hint- You could use
ice cream
and/or slushy ingredients for comets and cookie dough and/or non-cook fudge
ingredients for asteroids.) Use peer review to determine if the models
accurately portray
the physical attributes of a comet/asteroid.
Make a dry ice comet. Instructions can be found at
http://stardust.jpl.nasa.gov/classroom/activities/2-stardst-ch02.pdf
After showing students pictures of craters on the moon, provide materials (e.g. aluminum
pans, flour, marbles, etc.) and allow students to devise experiments on how to create
craters of varying depths and widths.
Hold a class discussion on how the Earth would be different if there were no comets,
meteors, or asteroids.
